did you test pressure first?

that really doesn't sound like a fuel pressure issue. that sounds like a cold start issue due to misreading temp sensor or something.

whats the temp sensor your talking about is it a common problem?
The temp sensor in the water pump. It is where the computer gets its info about coolant temp. Scanner data will easily confirm if it is working correctly. The harder way to check it is with a meter.
